				Hi, 
 
What is the default message expiry time ? If I do not change the expiration time of a message how long would it remain in the queue ? 
 
 
One more, if a persistent message expires (or will it expire ?) will it be discarded from the queue. 
 
 
Regards

				The default is -1, which means Unlimited;it will never expire.
 
 
A persistent message can expire, if you change the default value from Unlimited. Persistence simply means that until the message expires, if the QM goes down, the message will still be on the queue when the QM comes back up. _________________ Peter Potkay

				A message that has expired is never returned to an application ,so the value in the Expiry field of the message descriptor after a successful  MQGET  call is either greater than zero, or the special value MQEI_UNLIMITED. 
 
 
If a message is put on a remote queue, the message may expire (and be discarded) whilst it is on an intermediate transmission queue, before the message reaches the destination queue. |

				Hi There,
 
 
If I want to make a message Unlimited explicitly, how do I code it?
 
 
should I say something like this:
 
 
MQMD.Expiry = Unlimited OR is there any other way of coding this?
 
 
 
Thanx and appreciate your help |

				Hi Bower5932,
 
 
Thank you so much for your reply. 
 
 
In order to use MQMD.Expiry = MQEI_UNLIMITED, do I have to mention cmqc.h name in my application?
 
 
Once again, thanx a lot for your help.
